TO ALL WHOM IT MAY CONOERN:

Beit known that I, CHARLES V. WOERD, of Waltham, in the county ofMiddlesex, and State of Massechusetts, have invented a new and usefulImprovement in Stem-Winding and-Setting Watches; and I do hereby declarethat the following, taken in connection with the drawings whichaccompany and form part of this specilication, is a description of myinvention sufficient to enable those skilled in the art to practise it.

This invention is an improvement in the detail by which the movablelever carrying a shifting-pinion, and seen in my application for apatent which was allowed April 27, 1867, is changed from one to anotherposition, and is held securely in either position against accidentaldisplacement, the means employed for the purpose of shifting said leverbeing such as to give an eil`ective indication when the shifting-pinionis in gear with the time-trainrand preventing in such case the closingof the cover which shuts over and protects the crystal, hands, and dial.The drawings representing'an embodiment of my invention show the detailsin which my invention consists- Figure 1 presenting the parts in theposition. which they have when the gearing is in position for Windingonly, and

Figure 2 showing them as changed for setting the hands only.

These figures are plans of a full front plate of a wellknown variety ofWatch, but with all the parte removed therefrom which are unconnectedwith my invention.

Figure 3 is a sectional View, the section being talien on the line z z,seen in fig. 2.

The watch-plateis denoted by g, and the position of the pendant andpush-pin and stem-winder is indicated by the line y y, this being theaxis of the winding and setting-shaft otherwise not shown. The place forthe cannon-pinion is marked a, and the lever IJ, which is pivoted on thecentre of the wheel e, is intended to carry at its short end agear-wheel or pinion, which, while constantly meshing into gear c, is,by vibrating lever b, carried around gear c, and made to mesh into thecannon-pinion for the purpose of setting the hands, or into a gear onthe spring-barrel for the purpose of winding the watch. The piece m,seen in figs. l and 2, is designed to represent a portion of the outercasing of a watch, and from the junction of this case-piece inward tothe recess for gear e there is formed in the plate g a wide groove intowhich is fitted a slide, n, beneath the long arm 0f lever b, this slidehaving a. tongue or handle by which the slide n is moved out and in fromand toward the Centre of wheel c, the tongue which is marked 0 passingthrough a slot or cut made in the rim of m which adjoins the Watch-plateg,and resting on the surface of m, there being a cross-groove in thetongue o so that the slide can be drawn out and pushed in by a personsingern`nil. In said slide is an inclined slot into which projects thepin c inthe end of the long arm of the lever b, soA that it will be seenthat it is the action of the inclined surfaces oi' this slot on the pin/c which causes vibratory movement of lever b whenever the slide n isreciprocated. .A spring-latch or catch, j, is located as seen in thedrawings, and acts on or against a projection on the slide n and holdsit in either of its nornialpositions secure against change, except whenforce is designedly applied for the purpose to the. tongue 0. As the lidor case cover closes down upon the surface of m, it will be evident thatit cannot be shut when the tongue o is drawn out thereupon, as seen iniig. 2, which is the position it must assume' before thehands can beset, and the tongue o cannot be got at for the purpose of setting thehands till the lid or cover is opened to show a view of them. It willnow be apparent that as the Watch-case cannot be closed, after settingthe hands, till the gear on the short arm of lever b is swung out ofmesh with the cannon-pinion into mesh with the gear on thespring-barrel, the` movements ofthe time-train will not he likely to bedisturbed by the setting-train remaining in connect-ion with thetime-train, and Ait will also be obvious that when the watch-case isclosed the condition of the parts must be such that the watch can bewound at the stem.

I claim, for the purposes described, the slide arranged to operatesubstantially as set forth.
